Quote from Malcolm in Hal's Birthday
Reese: Didn't I tell you flowers were a great idea? Waiter: OK, we're all set. You have the Plaza burger, the main lobster, the porterhouse, large platter of French fries and the complete dessert cart. Your parents certainly have an interesting taste in food. Malcolm: Yeah, they do. Waiter: Actually, I'm gonna need one of your parents to sign that. Malcolm: I left the tip blank. Why don't you put in what you think is fair? Waiter: Bon appetit.
